Is this the full schema previously available at http://comicrack.cyolito.com/downloads/ComicRack/Support-Files/ComicInfoSchema.zip/ ?

If I remember correctly, I got it there, yes.

Could you explain the Number, Count, Volume tag?

Best to work with an example: Batman Volume 2 (DC Comics):

Number - the issue number; its String because some issues are not numbered as an Integer; see Batman 23.1

Count - total number of issues in this volume; for Batman example its "57"

Volume - the volume of the series; Batman example is "2" or "2011" (since there was a previous run in 1940 and followed in 2016)
